MOUNTING FOR EYEGLASSES.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed September 12, 1906. Serial No. 334,296.

T 0 all whom it may concern:

Be it knownthat I, GEORGE BAUsoH, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Mountings for E ye- 1 glasses, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description.

This invention relates to certain improvements in mountings foreye-glasses, and refers-more particularly to the structure of thespring-bow and manner of connecting it to the posts to which the lensesare attached.

The essential objects are, first to increase the general flexibility andresiliency of the "mounting, and particularly the bow-spring so as toafford greater scope of adjustment of the lenses to conform to differentconditions of the eyes without permanently bending or reconstructing themounting. In other words, I have sought to introduce a longer, andconsequently more resilient leverage in the active portions of thebowspring, and at the same time to enable the lenses to be adjustedtoward and from the eyes relatively to the bow of the spring withoutpermanently bending any portion of the bow-spring from its originalshape.

A further object is to adjustably clamp the ends of the bow-spring tothe posts between the box and lens clamps so as to afford as long aleverage as possible in the action of the ends of the bow-spring.

Other objects and uses will appear in the following description.

In the drawingsFigures 1, 2, and 3 are respectively enlarged top-planand front and rear elevations of my-irnproved mounting showing portionsof the lenses or eye-glasses attached thereto. Fig. 4 is a sectionalview taken on line 44, Fig. 2, showing the relative arrangement of oneend of the bowspring and post, and means for adjusting and clamping thespring to said post.

.As shown in the drawings, this mounting consists essentially of aone-piece bowspring 1 of comparatively light spring metal, having itscentral portion arched upwardly and forwardly tofit the nose, and itsopposite extremities deflected forwardly and adjustably secured to thecentral portions of suitable posts 2. Each of these posts is provided atone end with a lens clamp 3, and at its opposite or inner end with a box4, for receiving a shank of a noseguard 6 Each of the lens clampsconsists of a pair of ears adapted to clasp opposite faces of the,

lens, as a, said lens and ears being formed'of suitable apertures forreceiving a clamping bolt or screw 7 whereby the lens is rigidlyattached to the post. These clamps are provided. with the usual rimfingers -8- for engaging the periphery of the lens and bracing itagainst rocking movement upon its fastening screw 7.

Each of the posts -2-- projects radially from the lens and is providedwith an aperture 9- located between the clamp 3 and box 4 for receivingone end of the bow-spring 1, said aperture and the adjacent end of thebow-spring being disposed at substantially right angles to the plane ofthe lens to permit said lens to be adjusted toward and away from the eyeand relatively to the nose-pieces 6, or in other words,

the bow-spring is ad usted in the apertures 9 to different planesrelatively to the planes of the lenses so as to bring the eye glassescloser to or further away from the eyes when the bow is resting upon thenose.

Each of the boxes '4 is channeled vertically to receive the shank 5 ofthe nosepiece, said shank and post being provided with apertures forreceiving a clamping screw 10,the aperture in the post being threaded toengage said screw, which also engages the adjacent end of the bow-springto lock the post and bow-spring in their adjusted positions relativelyto each other.

In order to increase the leverage and re siliency of the spring, theportions of said spring oining the central arch to the offsets whichenter the posts, are bent in the form of loops '11 which introducesgreater flexibility and enables the lenses to be sprung apart, orforwardly and rearwardly, as well as vertically, with greater freedomthan would be possible if the ends of the arch of the bow entereddirectly into the posts.

The essential feature, however, of my invention is first, attaching ofthe ends of the bow-spring to the intermediate portions of the postsbetween the lens clamps and their boxes; second, the adjustability ofthe posts upon the ends of the bow-spring, or rather the adjacent endsof the bow-spring in the posts, and third, extending the drill-hole forthe screw lengthwise into the post a sufficient distance so that its endengages the portion of the bow-spring inserted therein, whereby the samescrew which fastens the nose-piece in the box is utilized to lock thepost and. the end of the bow-spring together.

What I claim is:

1. In a mounting for eye-glasses, a pair of posts each having a lensclamp at one end and a box at its opposite end, nose-pieces mounted inthe boxes and a bow-spring having its ends secured to the posts betweenthe boxes and lenses for increasing the leverage and resiliency betweenthe arch of thebow and its point of fastening to the lens posts.

2. In a mounting for eye-glasses, a pair of posts each having a lensclamped at one end and a channeled member on the opposite end,nose-pieces secured to said channels and a bow-springhaving its endsextended some distance beyond the nose-pieces and attached to said postsbetween their ends.

3. In a mounting for eye-glasses, a pair of lens posts having boxes ontheir ends and transverse apertures between boxes and lenses, incombination with a bow -spring having its ends secured in said aperturesand nose guards secured in said boxes.

4. In a mounting for eye-glasses, a pair of lens posts having boxes ontheir ends and transverse apertures between boxes and lens, incombination with a bow-spring having its ends adjustably secured in saidapertures and nose guards secured in said boxes.

5. In a mounting for eye glasses, a pair of lens posts attached at theirouter ends to their respective lenses, noseguards secured to the innerends of said lens posts, and a bow spring having its ends secured to thelens posts between the nose guards and points of attachment of the lensposts with the lenses.

In witness whereof I have hereunto set my hand this 1st day of September1906.
